Zac Hall:

Spotted by @StellaFudge on X, macOS Tahoe 26 includes a warning message when using Time Machine to back up a Mac to Apple router-connected storage.

The next major version of macOS will no longer support AirPort Disk, or other Time Capsule disks, for Time Machine backups.

I wonder if this is because they’re removing AFP entirely, after recently deprecating it in macOS 15.5.

Joe Rossignol:

Starting with macOS 27, [network Time Machine] backups will require a storage drive that supports more current file-sharing protocols like SMBv2 and SMBv3.

Time Capsules only support AFP and SMBv1, I think.

Update (2026-06-17): Hartley Charlton:

macOS 27 Golden Gate removes AFP support, ending Time Machine compatibility with Time Capsule after nearly two decades, but a community project from a Microsoft engineer offers a potential workaround for owners not yet ready to move on.
